RETORT FOR THE MANUFACTURE OF GAS.

SPECIFICATION forming part of Letters Patent No; 783,435, dated February28, 1905.

Application filed July 24,1903. Serial No. 166,904.

To (all whom it m/rr/y concern:

Be it known that I, GUs'rAv HORN, gas-engineer, a subject of the Emperorof Germany, residing at Brau'nschweig, in the Empire of Germany,(whosefull postal address is 23 Nordstrasse, Braunschweig aforesaid,) haveinvented new and useful Improvements in Retorts for the Manufacture ofGas, (for which applications have been made in Germany, dated January31, 1903, and in Great Britain, dated June 18, 1903,) of which thefollowing is'a specification.

This invention relates to retorts for the manufacture of gas which havechannels at the top or at the bottom, or at both.

According to this invention the wall between the retort and a channel isformed of plates of refractory material arranged in steps in such amanner that a space is left between each two adjacent plates. For thispurpose the plates may be provided with ribs or projections. their facesare inclined toward the mouth through which the charge is drawn, andthey project one over the other, so that no portion of the charge canobstruct the holes or spaces formed by the ribs. The plates may be fixedin the walls of the retort or may be laid loosely in recesses in theretort. It is especiall y advantageous to form the bottom of the upperchannel of loosely-laid plates, for on account of the free movement ofindividual plates the top of the retort will possess a yielding power,Thus no damage is done to the retort by excess of pressure caused by theswelling of a fresh charge, which is usually so prejudicial.

The annexed drawings illustrate apparatus constructed according to thisinvention.

Figure 1 is a vertical section of a furnace provided with the improvedretort. Fig. 2 is a vertical section of the furnace according to theline 00 w of Fig. 1. Fig. 3 is a trans verse section of the platesforming the wall between the channels and the charge-room of the retort.Fig.4 is a longitudinal section of the platesaccording to the line y yof Fig. 3.

Three (but this number may be varied) retorts a are heated by the samefurnace 1) and are each provided with two channels 6 and 0, one at thetop and the other at the bottom.

The position of the plates is such that Both channels communicate with agas-outlet pipe d. The top and the bottom of the retort, together withtheir channels, incline upward. The top Q and the bottom it of theretort are composed of plates Z, resting upon shoulders 2' or Ir; on theinside of the retort. As shown in Figs. 3 and 4 they are provided withribs 1n and n, so that while, on the one hand, they mutually supporteach other, on the other hand, free spaces are left between them throughwhich the gas generated passes. The shape of the said plates may varygreatly; but it must be such that while resting as securely as possibleand inclined toward the retort-mouth 0 the space between the platesallows the gas generated to pass freely away into the channels 6 and c,and the shape must also be such that the charge, ash, or the like cannotfall through the spaces into the bottom channel. The bottom channel mayadvantageously be used to pass vapor or the like through the layer ofcoke, and thus decompose the said vapor. For this purpose the vapor orthe like is led into the lower end of the channel o through a suitableconnecting-pipe 0. At the top end of the channel 0 communication withthe channel 6 is cut off by the damper f. Vapor or the like passing inthrough a is then compelled to divide up in its passage through thechannel 0 and to pass equally throughout the layer of coke. Inconsequence of the vapor being thus divided up the mass of coke is notcooled to so great an extent, as usual, when the whole of the vapor orthe like passes through the layer of coke at the same time.

I declare that what I claim is In a retort for the manufacture of gas,the combination with a furnace, retorts therein, channels in saidretorts at the top and bottom thereof, walls formed of plates providedwith ribs and arranged in steps between said channels and the interiorof the retort, substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

GUSTAV HORN.
